MRPC, a family-run business with its headquarters located in Butler, WI, is a one-stop shop for medical device assembly and parts. The company was founded in 1921, a time of significant industrial expansion in Milwaukee. MRPC provided rubber and thermoplastic components to some of the top manufacturers of electrical systems, plumbing supplies, power tools, small engines, and brewing and bottling equipment worldwide.

MRPC's reputation for quality, service, and delivery expanded along with its operations. Early on, the company produced rubber and plastic components for medical devices in addition to industrial goods. Company executives eventually redirected their attention toward medical components after realizing that the medical business offered a sizable potential promise.

In order to serve the medical device industry, MRPC started transforming several of its molding facilities into clean room manufacturing environments by the 1980s. At
